The 4 barrel and tripower engines also used different cams so carb to carb it isn't exactly an apples to apples comparison. However, Dick's comments above surely indicate the advantages of the tripower over a 4 barrel all other things being equal.

The only problem we've ever had with the tripower was the wrong body-to-base gaskets. The outboard carbs need a way to bleed off some air so vacuum doesn't pull them open before they are needed, the correct gaskets provide this air bleed. They were harder to find. We originally had a set used to rebuild the carbs but they sat around so long during the restoration that they dried out and shrank causing big vacuum leaks. Once good correct gaskets were used, it has run great with no fiddling. Ours had all the correct original carbs so we didn't even mess with the jets, just rebuilt them. Once good correct carbs are rebuilt, about the only adjustments are idle screws (center carb) and the mechanical linkage to determine when the outboard carbs should start opening up. If the linkage is not adjusted correctly it can open the outboards too early or too late. Pretty easy to test and adjust though. We had a set of original linkage used the last time the car had been running and matched the adjustment to that and honestly we never messed with it again, it worked great from the beginning following the restoration.
